The beluga, or white whale, is one of the smallest species of whale. Their distinctive color and prominent foreheads make them easily identifiable. Unlike most other whales, the beluga has a very flexible neck that enables it to nod and turn its head in all directions. Belugas generally live together in small groups known as pods. They are social animals and vocal communicators using a diversified language of clicks, whistles, and clangs. Belugas can also copy a variety of other sounds. These whales are common in the Arctic Ocean’s coastal waters, though they are found in subarctic waters as well. Arctic belugas migrate southward in large herds when the sea freezes over. Belugas feed on fish, crustaceans, and worms. The whale is related to the tusked „unicorn“ whale known as the narwhal. The beluga is not related to the sturgeon of the same name, which has been heavily fished for its famous caviar.

Christmas Island red crabs are famous throughout Australia and the world for their bright red color and for their spectacular annual migration to the sea. Millions of crabs become rivers of red as they move from the island’s interior rainforests to the ocean to breed and lay eggs. During migration, red crabs climb over and around obstacles in their way, following the same migration paths every year. Christmas Island red crabs live on Christmas Island in the Indian Ocean off Australia’s northern coast, about 240 miles (380 kilometers) south of Java, Indonesia. Red crabs must keep their bodies moist, so they wait for the rainy season to provide conditions that are ideal for the difficult journey. A single female can lay up to 100,000 eggs.

Bactrian camels have two humps on their backs where they store fat. Arabian camels, called dromedaries have only one hump, but both these types of camels use their stored fat as energy and water when they are far away from food and a freshwater source. Bactrians‘ nostrils close to block sand, and their bushy eyebrows and two rows of long eyelashes protect their eyes from blowing sand and ice. Baby camels are born with their eyes open and can run when only a few hours old. Camels move both legs on one side of the body forward at the same time, like giraffes and race horses. This is called pacing. The only truly wild camels that still exist are Bactrian camels. These herds survive in the Gobi Desert of Mongolia and China, but number less than 400. They are critically endangered in the wild.

The electric eel gets its name from its shocking abilities! Special organs in the eel’s body release powerful electric charges of up to 650 volts—that’s more than five times the power of a standard United States wall socket! Although eels have the power to be the bullies of the Amazon, they are actually not very aggressive animals. The eel uses its shock to stun prey and keep predators at bay. Electric eels are nocturnal, live in muddy, dark waters, and have poor eyesight. So instead of using eyes, electric eels emit a weak electric signal, which they use like radar to navigate, to find a mate, and to find prey. Once prey is found, electric eels will use a much stronger shock to stun prey, usually smaller fish. Electric eels can grow up to 8 feet (2.5 meters) in length. Despite their appearance, electric eels aren’t actually eels at all! They are more closely related to carp and catfish. The shock of an electric eel has been known to knock a horse off its feet. Now that’s shocking!
